A pipe rack assembly uses hot-dip galvanized trusses joined together by screw connections. The welded were manufactured with ASTM A572 gr.50 W steel profiles. Two of them fractured during the galvanizing bath. fractures presented typical characteristics LMAC — liquid metal-assisted cracking mechanism. In both cases, fracture was located in structural element base metal and followed fillet weld ...

Waste generation is a part of every technological process, including galvanizing. The presented paper deals with the characterization flue dust generated in process hot-dip galvanizing, and proposes possible methods for zinc recycling. released into atmosphere as white fume above bath, which caused by decomposition ammonium chloride present flux. This classified hazardous waste material particl...

Novak – Institute of Chemical Technology, Prague, Czech Republic This review article mainly describes the composition of intermetallic Fe Zn, i.e. zeta (ζ), delta (δ1k + δ1p), gamma1 (Γ1) and gamma (Γ) on galvanized steel during low temperature galvanization (t ~ 450 °C). It gives detail...
